An analytical derivation of the EMG signal's amplitude probability density function (EMG PDF) is presented and used to study how an signal builds-up, or fills, as degree muscle contraction increases. The PDF found change from a semi-degenerate distribution Laplacian-like finally Gaussian-like distribution.We present measure, filling factor, quantify which has been built-up. This factor calculated ratio two non-central moments rectified signal. curve mean shows progressive mostly linear...
Introduction: It has been shown that, for male subjects, the sEMG activity at low contraction forces is normally “pulsatile”, i.e., formed by a few large-amplitude MUPs, coming from most superficial motor units. The subcutaneous layer thickness, known to be greater in females than males, influences electrode detection volume. Here, we investigated influence of thickness on type (pulsatile vs. continuous) forces. Methods: Voluntary surface EMG signals were recorded quadriceps muscles healthy...
The EMG filling factor is an index to quantify the degree which signal has been filled. Here, we tested validity of such analyse process as contraction force was slowly increased.Surface signals were recorded from quadriceps muscles healthy subjects gradually increased 0 40% MVC. sEMG analyzed by measuring (calculated non-central moments rectified sEMG).(1) As increased, one or two prominent abrupt jumps in amplitude appeared between and 10% MVC all vastus lateralis medialis.

Abstract This study demonstrates that improvements in animal line selection by breeding enterprises exert a strong effect on carcass traits, meat quality and sensory characteristics of Serrano dry‐cured ham. A total 461 pigs from the offspring Duroc (DU) × Landrace (LD) sow mated with two DU boars Large White (LW) boar three were evaluated. The terminal sires significantly different ( P < 0.05) conformation, backfat thickness, ham loin yields, raw myoglobin concentration pigments formed...
Abstract Introduction The probability density function (PDF) of the surface electromyogram (sEMG) depends on contraction force. This dependence, however, has so far been investigated by having subject generate force at a few fixed percentages MVC. Here, we examined how shape sEMG PDF changes with when this was gradually increased from zero. Methods Voluntary EMG signals were recorded vastus lateralis healthy subjects as in continuous manner vs. step-wise fashion. filling process measuring...
Physicochemical characteristics, proteolysis, and cathepsin D activity of the Semimembranosus Biceps femoris muscles from commercial Iberian Serrano hams were evaluated.Total nitrogen, sodium chloride, fat, amino acid nitrogen contents only parameters physicochemical composition fractions that enabled ham to be differentiated in two considered.A wide variety polypeptides sarcoplasmic myofibrillar protein found Semimembranousus samples.The proteins present both varieties had molecular weights...
Introduction: There is no complete understanding of the way in which surface EMG signal progressively fills with motor unit potentials (MUPs) as contraction force increases slowly. We sought to investigate this sEMG filling process.Methods: Surface signals were recorded from quadriceps muscles healthy subjects was gradually increased 0 40% MVC. The process analyzed by measuring factor (calculated non-central moments rectified signal).Results: (1) As increased, one or two prominent abrupt...

EMG filling curve characterizes the process and probability density function (PDF) shape change for entire force range of a muscle. We aim to understand relation between physiological recording variables, resulting curves. thereby present an analytical simulation study explain how patterns relate specific changes in motor unit potential (MUP) waveforms (MU) firing rates, two main factors affecting PDF, but also conditions terms noise level. compare results with simulated cases verifying...
